HP Pavilion dv7-2019tx Graphics Card Driver

I have the latest Graphics card Driver for my HP Pavilion dv7-2019tx Notebook - Yet this Driver is from 2009 - I am sure newer drivers must exsist? Is there a newer driver available? - it is now almost 2011 and the latest Driver for a Radeon 4650 Graphics card was in August 2010 on the ATI webpage !
